DEVICE FOR WEIGHING AND SACKING GRAIN.

SPECIFICATION forming part of Letters Patent No. 377,513, dated February 7, 1888.

Application filed May 26, 1887. Serial No. 239,426. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES E. COLE, of

Somerville, in the county of Somerset and State'of New Jersey, have invented a new and Improved Device for Vveighing and Sacking Grain, of which the following is a full, clear, and exact description.

My invention relates to an improved device for weighing grain, and has for its object to provide a means whereby the grain may be automatically weighed and sacked upon passing from the thrashing-machine, and wherein the said machine may deliver the grain continuously to the device without interfering with the process of weighing.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a perspective view of the device; Fig. 2, a detail view thereof. Figs. 3 and 4 are detail views of the upper part of the apparatus, to better show the several positions of the swinging hopper-bottom in its several positions.

In carrying out the invention a frame, A, is provided consisting, preferably, of four uprights, a, braced and united at suitable points by horizontal beams (4. Within the main frame A, above the center, arectangular frame, B, is held in pivotal suspension by loops b, upon each side at one end, engaging pins driven or-otherwise fastened in the uprights a. The opposite end of said rectangular frame is supported from a parallel transverse bar, G,

pivoted at one end upon a pin, 0, driven in one upright above the said rectangular frame B, the said bar 0 being adapted to extend between the two uprights upon that side, as shown in Fig. l.- The pivotal connection between the end of the frame B and the bar 0 is preferably effected by the engagements of two staples, 0 0 secured, respectively, centrally to the upper edge of the frame and the contiguous lower edge of said bar. The pins supporting the frame B and the bar 0 may, if desired, be made V-shaped or with a knife-edge.

A box, D, having open top and bottom and downwardly-inclined sides and ends, and provided centrally upon opposing sides with pins d, is pivoted upon the swinging frame B by reason of the said pins d being entered intosuitable bearings, b, secured at the upper sides of said frame.

From each end of the aforesaid box D rods (2 are made to project perpendicularly downward, provided with apertures d at their lower end, through the ends of a platform, D, where the rods are detachabl y secured to said platform by pins d passing through the platform and also one of the aforesaid apertures d.

To the tapering sides and ends of the box D a series of hooks may be attached, whereby the bag to be filled is held in position beneath said box, as shown in Fig. 1, the bottom of the bag being adapted to rest upon the platform D. It will be observed that, the said platform being made adjustable, any ordinary size bag may be accommodated.

To the top of the main frame A a hopper, E, is attached, adapted to receive the grain, which hopper is made to project downward in the box D at one end thereof, the other end of said box being left entirely open, as seen in Fig. l. The outer side of the hopper at its reduced lower end facing the uncovered portion of the box is recessed the entire width, as at e, and immediately above said recess a transverse bar, 0, is hinged, adapted to extend beyond the hopper upon each side.

The bottom E of the hopper is made integral with or attached to said bar 6, and to one projecting end of the bar an arm, 6 is attached at right angles, adapted to be supported, when the bottomis closed, upon the bracket 8 fixed to one upright a. The said arm 6 is provided upon the upper outer edge with a weight, f. The extreme outer end of the arm 6 is slotted, and in said slot a tripping-rod, f, is pivoted.

A scale-beam, H, is pivotally suspended at one end within the frame A, the other end being adapted to extend parallel with the side of the hopper above the bar 6, to which the arm e is attached, and through a suitable staple fastened to said hopper, the extreme inner end of said scale-beam to the rear of its pivotal point being united bya link or chain with the non-pivotal end of the transverse bar 0. The scale-beam H is provided upon the lower edge at the outer side with a pin, it, adapted, when the grain is being weighed, to receive and support the tripping-rod f, as illustrated. The scale-beam is also provided with the usual sliding balance or weight, h.

Transversely in the hopper a shaft, K, is journaled, carrying upon one projecting end a pulley, 7c, and upon the other a cam, k, the cam being located above the scale-beam.

To the rear of the device a suitable elevator, M, is attached, adapted to convey the grain from the thrashing-machine into the hopper, the said elevator being driven from the ma chine by the shaft m and pulley m, from which motion is given the shaft K.

In operation the bag is attached and the weight placed properly upon the beam, (if oats are being thrashed, at seventy-five pounds, which represent two and one-half bushels.) The weighted arm and tripping-rod are now carried rearward until the tripping-rod engages and is held by the projecting pin upon the scale beam, as shown by full lines in Fig. 3. This action causes the hinged bar 6 to bring the attached bottom E of the hopper to a substantially vertical position, as shown in Fig. 1, from its closed or horizontal position, and the grain thereupon runs down uninterrupted into the bag. When sufficient grain has entered the bag to make two and one-half bushels, the scale-beam is raised by the pressure upon the platform D, carrying with it the tripping-rod f, as shown in dotted lines in Fig. 3. The said rod is then brought in contact with the revolving cam and thrown from its support, the weight upon the arm (2 carrying the said arm down to a horizontal position, thereby closing the bottom E and stopping the supply of grain, as clearly shown in Fig. 4. The filled sack may now be removed and another placed in position, when the door may be opened and its tripping-arm set, as in the first instance. The elevator continues at all times, when in operation, to deliver grain to the hopper, which may be made to hold three or more bushels.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combinatiomwith the swinging frame carrying a platform, an open box pivoted upon said frame, the pivoted transverse lever-bar united to said frame, and a seale-bcam connected with said lever-bar, of a hopper adapted to extend within said box, a bottom hinged to said hopper provided with an attached weighted arm, and a trigpingrod pivoted in said arm, and means for actuating said trippingrod, substantially as shown and described.

2. The combination, with the swinging frame, an adjustable platform suspended therefrom, an open box pivoted upon said frame. a pivoted transverse lever-bar united to said frame, and a scale-beam having an outwardly-pro jecting pin connected with said levcrbar, of a hopper adapted to extend downward in said boX, a bottom hinged to said hopper provided with an attached weighted arm and a tripping-rod pivoted in said arm, and means for actuating said tripping-rod and filling said hopper, substantially as herein shown and described.

8. The combination, with the main frame A, a swinging frame, 13, suspended within said main frame, an adjustable platform, D, supported from said swinging frame, and an open boxl), pivoted upon said frame, a transverse lever-bar, C, pivoted to said main frame and attached to the swinging frame,.and a scalebeam, H, having an ontwardly-cxtending pin, h, united with said lever-bar, of a hopper, E, extending downward in said box, a bottom, it, hinged to said hopper, provided with an attached weighted arm, 6-, and a pivoted tripping-rod,f, and a shaft journaled in said hopper carrying a cam, is, adapted to automatieallyactuate said tripping-rod, all adapted to operate substantiall y as herein set forth.
